Answer 1

从<select>代码中选择时，您应该使用Select class

WebElement dropdown = driver.findElement(By.id("courseLanguage")); // locate the dropdown
Select select = new Select(dropdown); // initialize select
select.selectByVisibleText("English"); // choose the option with "English" as text
// select.selectByValue("English"); // choose the option with "English" as value

它仍然会出现错误，因为“元素当前不可见，因此可能无法与”
进行交互

要确保在交互之前元素可见，请使用显式等待

// this will wait up to 10 seconds for the dropdown to be visible and will return the dropdown element
WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement dropdown = wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("courseLanguage")));

Select select = new Select(dropdown);
select.selectByVisibleText("English");

Answer 2

尝试使用findElements方法选择具有select标签的所有元素然后将所需元素传递给Select类，如下所示：

   List<WebElement> AllselectTags= driver.findElements(By.tagName("select"));   
     WebElement selectedElement = AllselectTags.get(0);
        Select s = new Select(selectedElement);
        s.selectByValue("English");

我试图在li标签的帮助下点击下拉列表中的一个选项但是没有得到输出我也没有收到任何错误
